he's high on his forehand, which people look for in a dressage horse.
His neck is a bit thick, which would make it hard for collection, but it's not really thick...he might have a little problem collection, but not much if any
Toes-out in the back, but it's fairly normal in horses so don't worry about that.
He also might toe -out in front, but that could be the way he's standing
He's sure a beauty! I love his face and his color!!
Personally I think he'd make a good low level dressage horse. It really depends though. If he hates doing dressage more than likely he won't suceed at it. Try to find things that he enjoys doing then pick.
